Roller slewing ring / angular-contact / axial / for public works, excavators and cranes - RLX HD
State of the art technology is specifically designed for Heavy Duty application requiring high capacity for axial loads & tilting moments. Thanks to double row of inclined long Rollers the slewing ring combine very high load capacity & compact geometry optimizing the Slewing Ring design and weight. A specific cage allow very smooth contacts in the raceway keeping friction torque to a minimum.Special sealing for dusty environment in Mining or corrosive atmosphere on Offshore vessels or platform are available. For application in contact with seawater Rollix thanks to specific welding process ensure the correct hardness on the seals contact face to match the require lifetime of your application.
The HD design can be used for Offshore crane, Aimuth Thrusters, PODS, Large Stackers Reclaimers, Bucket Wheels, Tunneling, Large Mining Excavators etc
For application with very high radial loads and high speeds for example Heave compensated winches in deep Offshore, Rollix designed a RLX HDR specifically for high radial loads, thanks to different angle of Rollers inclination. Our specific cage design and material secure highest rotation speed requirements.
